POTS Dial Peer Matching and Routing

I understand that there is a specific order in which CUCME processes POTS dial-peers - there's a great reference for the processing order here:http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a008010fed1.shtml

I still have a question though - for an inbound dial-peer, would multiple criteria mess up a dial-peer?

For instance, I have an analog device in FXS Port 0/0/1 of an IOS gateway.  I want calls that come in a PRI to be sent to this FXS port.  Could I use the following dial-peer for the outbound calls?  (Some digits replaced with "X" for confidentiality)

dial-peer voice 205 pots

description Dial-Peer for Fax Line 269-488-XXXX

incoming called-number 269488XXXX

port 0/0/1

dial-peer voice 204 ports

incoming called-number .

port 0/1/0:23

I want the call to be sent TO port 0/0/1, but I'm worried that the " incoming called-number 269488XXXX" will override the general "incoming called-number ." line on dial-peer 204, and the system will get confused because it will also expect that it can match the "port" command on dial-peer 205 - so that it would expect that it will also RECEIVE the call on the FXS port.  Basically, I'm thinking that dial-peer 205 will match inbound, and it will then look at the entire dial-peer, and try to look for a call coming from the FXS port, and therefore, break.  Does that sound right?  Or, since "port 0/0/1" is also a dial-peer matching criteria, but is NOT getting matched in this instance, will it ignore that line?

Thank you for any help you might be able to offer!

Re: POTS Dial Peer Matching and Routing

Dial-peer 205 will match only in when some one dials 269488xxxx , this is explicit match.

Your dial-peers are not acting as overlapping, so you don't have to worry.

You should change the config on this dial-peer to this..

dial-peer voice 205 pots

description Dial-Peer for Fax Line 269-488-XXXX

destination-pattern 269488XXXX

port 0/0/1

You use the destination-pattern to match on the outbound leg
